Question

Hi All i have the following string :

$sortable='record_69#record_83#record_70##'

preg_match_all('[0-9]', $sortable, $result, PREG_PATTERN_ORDER);
     print_r($result);

but the result is Array ( [0] => Array ( ) ) i wnat $result to be like $result[0]=69......

Thank you

Answer 1

The pattern [0-9] takes only one number. You want to select more than one, so you have to use a quantifier :

preg_match_all('/record_([0-9]+)#/', $sortable, $result, PREG_PATTERN_ORDER);

You also need to add delimiters (/ in this case), and parenthesis to capture the numbers.

Answer 2

preg_match_all（'[0-9] +'，$ sortable，$ result，PREG_PATTERN_ORDER）;

Answer 3

<?php 
$sortable = "record_69#record_83#record_70#";
preg_match_all("/(\\d+)/", $sortable, $result, PREG_PATTERN_ORDER);

echo "<pre>";
print_r($result);
echo "</pre>";
?>
